Image Quality for Near-Eye Display Based on Holographic Waveguides
Applied Sciences, 2022 The paper analyzes the image quality in augmented reality display based on holographic waveguides. Brightness, brightness non-uniformity, image noise, etc., depend on the parameters of the waveguide substrate, the configuration, and the relief shape of ...

HoloBeam: Paper-Thin Near-Eye Displays
2023 IEEE Conference Virtual Reality and 3D User Interfaces (VR), 2023 An emerging alternative to conventional Augmented Reality (AR) glasses designs, Beaming displays promise slim AR glasses free from challenging design trade-offs, including battery-related limits or computational budget-related issues. These beaming displays remove active components such as batteries and electronics from AR glasses and move them to a ...

Foveated holographic near-eye 3D display
Optics Express, 2020 We present a foveated rendering method to accelerate the amplitude-only computer-generated hologram (AO-CGH) calculation in a holographic near-eye 3D display. For a given target image, we compute a high-resolution foveal region and a low-resolution peripheral region with dramatically reduced pixel numbers.

Geometric Lightguide for Near-eye Light Field Display
Optics Express, 2023 Most near-eye displays with one fixed focal plane suffer from the vergence–accommodation conflict and cause visual discomfort to users. In contrast, light field displays can provide natural and comfortable 3D visual sensation to users without the conflict.

Depth-Enhanced Holographic Super Multi-View Maxwellian Display Based on Variable Filter Aperture
Micromachines, 2023 The super multi-view (SMV) near-eye display (NED) effectively provides depth cues for three-dimensional (3D) displays by projecting multiple viewpoint images or parallax images onto the retina simultaneously. Previous SMV NED suffers from a limited depth

Holographic Near-Eye 3D Display Method Based on Large-Size Hologram
Frontiers in Materials, 2021 In this paper, we propose a holographic near-eye 3D display method based on large-size computer-generated hologram (CGH). The reconstructed image with a large viewing angle is obtained by using a time multiplexing and spatial tiling system.
